Dental implant system

Abstract

An abutment for dental implant systems of the kind suitable to be associated to a dental implant. The abutment has an inlay, and the inlay is provided at its upper part with an external profile having one or more shoulders for connecting and permanently jointing the inlay to the abutment. Further, the inlay may be shaped such that it is completely surrounded by the abutment in the assembled state of the dental implant system.

What is claimed is: 
     
       1. An abutment for dental implant systems suitable to be associated to a dental implant,
 wherein the abutment comprises an inlay, 
 the inlay comprising:
 an upper part having an external profile comprising means for connecting and permanently joining the inlay to the abutment; 
 a bottom part configured to be inserted into a neck portion of the dental implant; and 
 a downwardly facing shoulder extending radially away and downwardly from the upper part, configured for engaging an upper surface of the neck portion, 
 
 wherein the inlay is shaped such that said inlay is not visible laterally when said bottom part is inserted entirely into the neck portion of the dental implant. 
 
     
     
       2. The abutment according to  claim 1 , wherein the abutment is molded around the means for connecting and permanently jointing, or wherein the means for connecting and permanently jointing are molded into the abutment. 
     
     
       3. The abutment according to  claim 1 , wherein the means for connecting and permanently jointing the inlay to the abutment comprises a plurality of shoulders interspaced by sections of the inlay having a smaller diameter than that of the shoulders. 
     
     
       4. The abutment according to  claim 1 , wherein said downward facing shoulder comprises a contacting surface suitable to abut on an upper surface of a neck portion of the dental implant. 
     
     
       5. The abutment according to  claim 4 , wherein the contacting surface of the downward facing shoulder completely overlaps the upper surface of the dental implant. 
     
     
       6. The abutment according to  claim 4 , wherein the contacting surface of the downward facing shoulder partially overlaps the upper surface of the dental implant. 
     
     
       7. The abutment according to  claim 1 , wherein the abutment is a provisional abutment or a healing abutment, and/or wherein the abutment has an emergence profile. 
     
     
       8. The abutment according to  claim 7 , wherein the emergence profile is either customizable by a dental surgeon or conforms the topology of the implant site of a particular patient. 
     
     
       9. The abutment according to  claim 1 , wherein the downward facing shoulder of the inlay has a lateral edge which is parallel to a longitudinal axis of the abutment. 
     
     
       10. The abutment of  claim 9 , wherein the lateral edge of the downward facing shoulder of the inlay is spaced from the exterior surface of the abutment. 
     
     
       11. The abutment according to  claim 1 , wherein the downward facing shoulder of the inlay has a lateral edge which is inclined in respect to a longitudinal axis of the abutment. 
     
     
       12. The invention according to  claim 1 , wherein the inlay is made of a material, which has higher mechanical characteristics with respect to the mechanical characteristics of the abutment to which said inlay is coupled. 
     
     
       13. The invention according to  claim 12 , wherein the abutment is made of plastic or ceramic materials and said inlay is made of titanium, titanium alloys, steel, gold, ceramic, reinforced plastic material or also composite fibers. 
     
     
       14. A dental implant system comprising a dental implant, an abutment and a connection screw suitable to steadily join the abutment and the dental implant together,
 wherein the dental implant system further comprises an inlay insertable within a neck portion of the dental implant, and 
 wherein the inlay comprises an upper part having an external profile comprising means for connecting and permanently joining the inlay to the abutment, a bottom part configured to be inserted into the neck portion of the dental implant, and a downward facing shoulder extending radially away and downwardly from the upper part and being configured for engaging an upper surface of the neck portion, the inlay being shaped such that said inlay is not visible laterally when said bottom part is inserted entirely into the neck portion of the dental implant. 
 
     
     
       15. The dental implant system according to  claim 14 , wherein the inlay has a bottom part provided with anti-rotational means. 
     
     
       16. The dental implant system according to  claim 15 , wherein the anti-rotational means comprise a polygonal element. 
     
     
       17. The dental implant system according to  claim 14 , wherein the means for connecting and permanently jointing the inlay to the abutment comprises a plurality of shoulders interspaced by sections of the inlay having a smaller diameter than that of the shoulders. 
     
     
       18. The dental implant system according to  claim 14 , wherein the abutment is a provisional abutment or a healing abutment, and/or wherein the abutment has an emergence profile. 
     
     
       19. The dental implant system according to  claim 18 , wherein the emergence profile is customizable by a dental surgeon or conforms the topology of the implant site of a particular patient. 
     
     
       20. A dental implant system comprising a dental implant, an abutment and a connection screw suitable to steadily join the abutment and the dental implant together,
 wherein the dental implant system further comprises an inlay insertable within a neck portion of the dental implant, 
 wherein the inlay is completely included inside the dental implant system and laterally invisible, so that no part of the inlay faces the natural tissues surrounding the implant, and 
 wherein the inlay comprises an upper part having an external profile comprising means for connecting and permanently joining the inlay to the abutment, a bottom part configured to be inserted into the neck portion of the dental implant, and a downward facing shoulder extending radially away and downwardly from the upper part and being configured for engaging an upper surface of the neck portion.
